Answer:
88/4 and 48/4
Step-by-step explanation:
88 + 48 = 136
136/4 = 34
= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
Answer: D. 94.25 in²
Step-by-step explanation:
To find the total area, we will break the shape up into two different parts.
[] The rounded part is 39.25 in². Let us assume the rounded part is exactly half of a circle.
Area of a circle:
A = πr²
Use 3.14 for pi:
A = (3.14)r²
Find the radius:
d / 2 = r, 10 / 2 = 5 in
Subsittue:
A = (3.14)(5)²
A = 78.5 in²
Divide by 2 since it is only half:
78.5 in² / 2 = 39.25 in²
[] The triangle is 55 in².
Area of a triangle:
A = b*h/2
A = 11 * 10 / 2
A = 110 / 2
A = 55 in²
[] Total area. We will add the two parts together.
55 in² + 39.25 in² = 94.25 in²
25 is the length of x, using the 30-60-90 special triangle method
Answer:
94 boxes of samoas
131 boxes of thin mints
Step-by-step explanation:
m=mints
s=samoas
s+m=225 m=225-s
s(2.5)+m(3)=628
2.5s+3m=628
substitute for m
2.5s+3(225-s)=628
2.5s+675-3s=628
reduce
-0.5s=-47
s=94
m=131
